XMT 350 CC/CV & Optima Pulse vs XMT 350 MPa

Which is better, a XMT 350 CC/CV with an Optima Pulse control or a XMT 350 MPa? I ask this because I have the XMT 350 CC/CV and am considering combining it with a possible Optima purchase for use with my 30A Spoolmatic for use on thin (17 or 18 ga.) AL . Is the MPa a whole bunch better, or just the same?

I use a XMT 350 MPa with a 30A Spoolmatic on aluminum daily at work, mostly 1/8" Alum and thicker. It's a great machine, the thinnest I have welded is 14 ga Alum. (If I remember correctly)Should have used a spool of smaller filler but didn't have any, still seemed to work well though. I have no experience with the 350 CC/CV so I can't make a direct comparison, sorry.

Thanks very much for your reply. Have you ever used the 30A with a Miller Optima pulser connected to any power source? If so how did it compare with the pulser built into the MPa? I'm trying to decide whether to splurge on an Optima. I might get an Optima if it's pulse abilities are equal to or better than the MPa's.
